"I? STATES ALBERT BROADMEYER, OF HARRISBURG, PENNSYLVANIA, ASSIGNOR TO W. O. HIGKOK MFG. CQIMPANY, 01E HARRISBURG, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

Application filed July 2,

To all 107mm it may concern:

Be it known that I, ALBERT BnoAnMnYnn, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Beams for Ruling Pens, of which the following is a specification.

The present invention relates to the struc ture of beams for holding ruling pens, and the object is to provide a simple beam of a novel structure that will effectively hold. the pens in place and will permit of their relative adjustment without disarranging the position of the beam and thus requiring its readjustment.

In the accompanying drawing:

Figure 1 is a perspective view of a portion of the novel beam,

Figure ,2 is a plan view of the same, with parts broken away.

In the embodiment disclosed a main bar 3 is provided which is preferably of metal, and located thereon is a clamping bar 1. The clamping bar 1 has its rear portion fiat upon the main bar 3, and has its intermediate portion cut-away as illustrated at 5, and thus spaced from the main bar. The front portion is also cut-away, as indicated at 6, the cut 6 being deeper than the cut 5. Clamping bolts 7 pass through the clamping bar 4- and intersect the cut-away portion 5. These bolts are threaded, as indicated at 8, into the main bar 3, and have heads 9 at their upper ends seated in sockets 10, "formed in the upper side of the clamping bar.

A lower pen clamping jaw 11 is provided, having a rearwardly extending tongue 12 that engaged in the cut-away portion 6. The main body of this clamping jaw abuts against the front edge of the main bar 3, as illustrated at 13. This clumping jaw has its front end tapered, and has its upper surface in rear of its front margin cut-away, as illustrated at 11-. An upper pen clamping jaw 15 lies upon the lower jaw 11, and has its rear edge abutted against the front edge of the bar a. This clamping jaw 15 has a cut-away intermediate portion 16 overlying the cut-away portion 14: of the lower Bolts 17 having heads 18 embedded in the lower side of the lower jaw, extend upwardly through both jaws and the cut-away portions 14: and 16 thereof The upper threaded ends BEAM FOR RULING PENS.

1925. Serial No. 41,162.

of these bolts are located in sockets 19 and in said sockets are clamping nuts 20 threaded on the upper ends of the bolts. A cover plate 21, preferably of sheet metal, extends over the top of the upper clamping bar 4: and the upper jaw 15, thus covering the joint between the two. The plate 21 is hinged, as shown at 22, to the rear side of the upper clamping bar 4.

lVith this structure, it will be evident that if the cover plate 21 is swung rearwardly the nuts 20 are readily available and pens, as 23, can be introduced between the jaws, easily adjusted, and readily clamped. The set of jaws may also be attached to and removed from the beam proper as an entity and may be adjusted with respect thereto. The heads of the clamping bolts 19 are readily available for loosening or tightening said bolts.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the ad vantages of the invention.

What I claim, is

1. A pen beam for ruling machines, comprising a main bar, a clamping bar, a pen holding jaw clamped by and between the main bar and clamping bar, and a second pen clan'iping jaw coacting with the first jaw to clamp the pens.

2. A pen beam for ruling machines, comprising a mainv bar, a clamping bar,a pen holding jaw clamped by and between the main bar and clan'ipiug bar, and a second pen clamping jaw coacting with the first jaw and separate from the main bar and clamping bar.

3. A pen beam for ruling machines, comprising a main bar, a clamping bar thereon and coacting therewith, a pen clamping aw having a tongue located between and clamped by the bars, and a second pen clamping jaw on the first jaw in advance thereof.

4. A pen beam for ruling machines, com prising a main bar, a clamping bar located on the upper side thereof, clamping bolts connecting the bars and having operating heads on their upper ends, a pen clamping jaw having a tongue located between and clamped by the bars, a secend pen clamping jaw 0n the first jaw in advance thereof, and clamping bolts connecting the aws and having operating means on the upper ends.

5. A pen beam for ruling machines comprising a main bar, a clamping bar thereon and coacting therewith, a pen clamping jaw havin a tolwue located between and clam ed.

by the bars aisecond .pen clamping jaw on the first aw lIl advance thereof, and a cover plate hlnged t0 the clamping bar and extending over the 01nt between sald bar and upper beam clamping aw.

In testimony whereof, I atfie; my elgnature.

ALBERT BROADMEYER.
